Benefits of technology
The present invention provides a method, computer program product, and system for routing messages over a computer network using multiple database systems. The method allows for the preservation of routing information within the internet message prefix, which is transparent to the selected communication protocol. This is useful in environments where different protocols are required for different database systems. The invention allows for the efficient routing of messages to clients and provides various advantages and features.
Problems solved by technology
Therefore, many enterprises are faced with the challenge of making core business applications currently running on legacy systems available to the Internet.
Whenever the back-end DBMS is non-IMS and the front-end DBMS is IMS a serious problem, briefly discussed infra, may arise.
In this set of circumstances, the result message generated by the back-end DBMS is routed back to the originating front-end DBMS; however, the result message may be void of routing information for the originating client request.
If so, such a result message is referred to as an “orphaned” message, as it is not possible to return the message to the originating client.

A message is received in a first form for communicating with a first DBMS wherein the first form comprises an internet message prefix and a data portion, the internet message prefix comprising routing information for a client. The message is modified into a second form wherein the client routing information is integrated into the data portion of the message and wherein the second form of the message is utilized to communicate with a second DBMS. A result message generated by the second DBMS is received wherein the result message comprises a result data portion, the result data portion including the routing information. The result message is modified to the first form wherein the result message comprises the internet message prefix, the internet message prefix comprising the client routing information obtained from the result data portion. In this manner, the result message may be routed to the client.
Description
FIELD OF INVENTION [0001] The present invention relates generally to the routing of messages over a computer network. More specifically, the present invention relates to a method, computer program product and system for the preservation of routing information in the prefix portion of a message independent from the communication protocol being utilized. BACKGROUND [0002] In the past, leading-edge commercial applications with high performance and reliability requirements were typically run on legacy systems, such as Information Management System (IMS). (IMS is a trademark of International Business Machines Corporation in the United States, other countries, or both.). Today, the near universal acceptance of Web Technologies increases the demands for communication-based applications; however, even in today's distributed computing environments with Web based applications, it is very common for the data associated with WEB based applications to be legacy data (i.e. data that is managed by...
